Maybe I'm overlooking something very obvious, but why don't you
simply change your function to something like this:
int orderWordsByUseInDictionary (NSDictionary
*indexedWordsWithCounts, id tWord1, id tWord2, void * reverse )
and then make use of indexedWordsWithCounts within its body?
Won't work, that way the function has a different signature and
can't be passed to sortedArrayUsingFunction:context: anymore. What he
really wants to do, is pass the dictionary in the context parameter
(named "reverse" in that prototype). Whatever used to be passed in
context would just be added to the dictionary as well (Or you would
have a dictionary that in turn contains the indexedWordsWithCounts
dictionary *and* reverse, or you could use a struct containing both,
or whatever). That's what the context parameter is for.
